Name and Avatar not displaying on remove device

I have two apps ( Host and Client ) that both use Jitsi Meet SDK for iOS. When starting a session, we populate the user name and user Avatar and make a connection. Connection works fine.

However, on one device both Avatar’s display but only the user name of the remote device when the thumbnail is selected. On the other device, neither avatars display and only the name of the remote device.

Any suggestions on what might be happening or areas we could investigate?
